Light weight aggregate concrete uses the aggregates having low specific gravity when contrasted with the normal aggregates. Bottom ash is utilized to produce the light weight aggregates. The raw material first crushed, mixed with cement and lime and afterward pelletized with water followed by solidifying by sintering or cold bond technique.

Abstract: Many research has been conducted in manufacturing aggregates artificially using industrial waste. Artificial aggregates serve two purposes (i.e.) one reducing the weight of concrete, and another is overcoming the disposal problem of industrial waste. Weight of coarse aggregate increases the density of concrete and thereby increasing the overall self weight of …
